CALCULATING MACHINE Application led February 16, 192.2. Serial No. 536,960;

To all whom it may concern;

Beit known that I, ARTHUR F. Poom, citizen ot the United States, and resident of Kenilworth, in the county of Cook and State ot Illinois, have invented certain new and useful Impmvements in Calculating Machines, of which the following isa specification.

My invention relates to calculating machines and it has tor its principal object to provi-de certain improvements in clearance proof mechanism for such machines. I have shown my invention applied toa combined typewriting and .calculating machine in which the totalizers are cleared by setting the actuators for subtraction and copying the total by operating the numeral keys. In

machines of this character, the totalizer will always come to zero provided the total has been correctly copied.

My invcntlon has for one of its principal objects to provide improved means for notifying the operator in case a predetermined one of aplurality of totalizers has not been cleared at the time when it should have been. Another object ofniy invention is to provide in addition. to a lock other means of notifying the operatorthat a totalizer is not cleared, namely, a. visual indicator. In the particular machine shown in the drawings there are a plurality of these indicators, one for each ofthe totalizers whose clearance is to be proven, so that in case the lock has been operated to notify the operator that a totalizer is not clear the appropriate one of these indicators will show which totalizer it isl that should have been cleared and has not.

To the above and other ends my invention consists in certain features of construction and combinations and arrangements of parts, all of which will'be fully set forth herein and particularly pointed out in the claims.

One instance ot my invention is illustrated in the accompanying drawings which show said invention applied to a Remington accounting imichine which, except as hereinaftcr described. may be constructed in accordance with the patent to John C. Wahl for calculating machines, No. 1,849,024, patented August 10,1920. In said dranf'ings- Figure 1 is a conventional front elevation of so much oi said machine as is necessary to illustrate the application of my invention thereto.

One form of the Remington accounting machine including a single cross footin totalizer in combination with a plurality o vertical totalizers, is shown and described in the patent to John C. Vahl, No. 1,27 0,471 for calculating machines, patented June 25, 1918. The machine shown in the Patent No. 1,349,024 above referred to, is an extension of that shown in No. 1,270,471 to 4provide for a plurality ot' cross footing totalizers in place of the single cross footing totalizer of the earlier patent. From these two patents together the construction of the machine to which my improvements are here shown applied. can be fully understood.

The Remington accounting machine includes a Remington typewriter which is notshown in detail in the present drawing but which includes printing keys 10, types 11 operated by said keys, and a platen 12 mounted in a carriage and on which the paper is placed. The principal frame piece oi the lVahl calculating mechanism is a. long casting 13 secured by certain brackets to the top plate 14 of the typewriter, Fig. 4. Running on certain wheels 9 carried by the frame piece 13 at the middle of the machine is a main totalizer truck 15, Fig. 2, which is connected at its ends to the type writer carriage to travel in unison therewith. I have shown seven t'otalizers, 1, 2, 3, 4; 5,'0 and 7, mounted on this truck to calculate numbers written in seven columns on the paper. These totalizers are operated in the well-known manner by a master wheel, not shown, but which is part of the actuator' mechanism which is operated by the numeral keys 10 of the typewriter.

Two cross totalizers 23 and 24 are mounted on a cross truck 25 in position to be operated, the first by a master wheel 26, and the other by a master wheel 27, which master wheels are operated and controlled in the manner described in the Patent No. 1,349,024 above referred to. Said t-ruck 25 runs by ball bearings onl rails 28 secured at their ends to frame plates 3() and 31 which frame plates are secured to the main frame bar 13. The truck 25 is intermittently drawn toward the left by means ot' a hook 32 which is caught up by one after another of the vertical totalizers and is released at the end of each adding column; and said truck when released is drawn back to its right-hand position shown in Fig. 1 by means of a spring 33. When so drawn back it is arrested by a bar 34 on the truck striking against a lever 35 pivoted at 36 to the frame plate 31 and pressing said lever flat against said frame plate 31, as shown in Fig. 1. The. lever 35 is normally held by a spring 3T a short distance to the left of plate 31 as shown in Figure 2. The lever 35 has connected thereto a slide bar or link 38 which at its left-hand end is articulatedr with a bell crank 40 which is one of the controlling devices of a certain. lock which lock is fully described in the vWahl patents hereinbefore referred to.

Said lock is also controlled in part by a certain roller 41, Fig. 6, which is normall pressed upward by a spring but which, when one of the vertical totalizers is brought by the travel of the carriage into a calculating zone over its master wheel, is depressed by a trackway 42 constituting part of the framework ,of said totalizer. The construction ot' the lock is such that whenever one o1c the vertical totalizers 1--7 is over the main master wheel, and when therefore the roller 41 is depressed and if at that time the cross truck has not been hooked up to said totalizer, as it should be, but stands in its right-hand position as shown in Fig. 1, then the keys of the machine will be locked against operation; but under other conditions this lock will be ineffective. The lock is operated by the joint act-ion of the roller 41 and the` lever 35, and

is effective when said roller is depressed and said lever 4is in its right-hand position. rlhis lock is thus particularly mentioned because in the present instance I use it in my clearance prooi' mechanism. but i have not illustrated the lock in detail partly because its construction is well-known and partly because any other suitable locking means can be employed instead. E use this one .because it happens to be in the machine and is convenient for my purpose.

The master wheels 26 and 27 are each capable of being rotated in one direction for addition and in the reverse direction for subtraction, and in the iahl machine said wheels are thus controlled by certain change gear mechanism which in turn can be controlled b a variety of means described in the Wah patents above cited. One of said means consists of an automatic control, part of which is shown in the drawing. As shown in Figs. 1, 2 and 6, each of the vertical totalizers has two cam plates, ai front plate 43 and a rear plate 44, said plates secured to the framework of the totalizer by a screw 45 and other means fully described in Patent No. 1,349,024. The plate 43 controls a follower' roller .46 and the plate 44 a follower roller 4T, said rollers boing pressed upward by springs and being depressed on occasion by the respective cam pla-tes. The roller 46 is connected to the change-gear mechanism which controls the master wheel 26 for the cross totalizer 23. The roller 47 is connected with the change gear which controls the master wheel 27 for the cross totalizer 24. The construction is such that when one of these rollers is in its highest position the corresponding master wheel will be rotated for addition; when said roller is in its lowest position said master wheel will be rotated reversely for subtraction and when said roller is in an intermediate or middle position said master wheel will be disconnected so as not.to be .turned when the keys are operated. The plates 43 and 44 have provision for adjustment to the several positions described, as fully set forth in Pat-ent No. 1,349,024. v y

By way of illustration, the machine is shown in Fig. 1 set up preparatory to computing an account in the following form:

Debits. Credits.

Total Total Contra debits. credits. Balances Labor. Material. Cash. account The malit) at the end of the Writing of column 6 chine is set up so that the various columns are added respectively in the vertical totalizers 1, 2, 3, 4, 5, 6 and 7. The various cams 43 and. 44 are so setvor adjusted that at the same time all items in columns 1 and 2 are added in cross totalizer 23 and all items in columns 3 and 4 are added in cross totalizer 24. The totals indicated on these cross totalizers are copied respectively in columns 5 and 6. In `order to get the balance for column 7 the machine is so set that when Writing column 5, that is the total debits,`neither of the cross totalizers is operated, the amount Written in column l6 is subtracted from both cross totalizers; and the amount written `in column 7 is subtracted from totalizer 23. As the amount Written in column 6 is the amount that was indicated in totalizer 24, the act of writing column 6 should clear that totalizer and at the same time the total credits will be sub-v tracted from the amount indicated on totalizer 23. Said totalizer 23 will then show the difference `between the total credits and the total debits. This difference is then copied in column 7 and subtracted from totalizer 23. In order to carry out this` scheme of addition and subtraction the cam plates 43 and 44 on the several totalizers 16-22 have been set as indicatedin Fig. 1. When one of these cams is set in its highest position it causes addition yin the corresponding one of the two totalizers and when the cam is set in its middle position it causes the corresponding totalizer to be disconnected. For example, on each of totalizers 1 and 2 the frontcam 43 is set up for addition and the rear cam 44 is set in its middle position for disconnect so as to cause amounts added on these two registers to be added on the cross totalizer 23 and not be registered at all in totalizer 24. In columns 3 and 4 this relation is reversed, Whereas in column 5 both cams are set at disconnect position. In column 6 both are at subtract and in column 7 43 is at subtract and 44 at disconnect.

It will be perceived that if the work Ais correctly done totalizer 24 will .come to zero and totalizcr 23 will come to zero, lat the end of the writing of column"7. .I have therefore provided means for notifying the operator in case the totalizer 23 is not clear at the' end of column 6 and in case totalizer 24 is not clear at the end of columnx 7. This example is given merely by way of illustration. Thejclearance test could be made to take place at anyr other point de- -sired in the program of operation by a simple adjustment of the vertical totalizers, as 'will hereinafter appear. l

My clearance proof mechanism includes mcans'.for automatically locking the keys immediately after` the writing of the last digit in any 'computing columnv Where it is desired to test, for clearance.V In the present instance the `mechanism is Set to 'lock 24 is then clear it will, during its jump-v back to the right at the end-of column 6, release the lock. `In the same way at the end of column 7 totalizer 23 \if clear will release the lock.

The means for locking the keysv comprises means for operating the lever 35 so as to press said lever to its locking position independently. of the truck 25, so that therefore even 1f said truck is properly hooked up to Write a number the keys will be found locked.A A frame platej is secured to the casting 13 by means of screws 51 in such` fashion that it extends parallel to said casting and behind it as shownin Fig. 4. A post- 52 in the vnature `of a-pivot screw is screwed into this frame lplate and it has pivoted thereon two threearmed levers 53 `and. 54 best shownin Fig. 3. Each of said levers has one of its arms extending downward and termmatlng in av lug 55 which lies infront of the locking lever in such positions that if either of the levers 53 or 54 Were swung'toward the right from the position shown in Fig. 2 it will operate said lever 35 to lock the keys. Said levers are normally held in their inactive positions shown in 'Fig'. 2 by means ot'v two latch levers 56 and 57 pivoted on a pivot stud 53 projecting forward 'from' the plate Each of said latch levers has'a horizontally extending arm having at its end a notch in which normally rests a lug 60 bent off from the upper end of one of the levers 53, '54.

A spring 61 is connected to "each lever 53 or 54 above its pivot and to the corresponda ing latch lever beneath the pivot of .the latter and this springr performs the double function of holding the latch lever in latching position and of moving the lock lever 53, 54 to locking position when released from its latch. Each of the levers 56 and 57 has an upstanding arm in 'position to be operated, the first by a push wire 62 and the last y by a ush Wire 63, these Wires passing througi suitable holes in an ear 64 bent oil from the plate 50 and standing with their ends in such position that if one ot them be moved toward the right it will release the corresponding latch lever.

Near the middle of the machine a sheet metal bracket is secured to the top of the casting 13 by means of screws 66 and this bracket. is bent first upward and then forward to produce an overhangingv portion to which is secured a pivot screw 67 here shown as provided with a lock nut 68. This screw hangs downward' and is headed at its lower end and it has pivoted thereon two bell cranks .70 and 7l, the former above the latter as shown. llach ot these bcllcranks is made of sheet metal with a double bend in it so as to give it two points ot' ivotal bearing on the screw or post 67. lach of said bell cranks has the lower plane thereof extending rearward through a suitable opening in the bracket Gso as to constitute a reai-,

wardly extending arm of the bell crank and the push wire 6'2 is pivoted to the upper one of these arms and the push wire 63 to the lower one. Each of the bell cranks has its upper level or plane prolonged toward the leftl to constitute the other` arm ot the lever and to these arms, dogs 72 and 7 3 are pivoted 74. Each of said dogs is connected behind its pivot to a spring 75 tending to rock the dog about its pivot and the rocking o said dog by said spring is limited by a pin 76 projecting upward from said dog and striking against the lever arm. Each lever is controlled as a whole by a tension spring 77 tending to rock the levers counter-clockwise as seen from above.

The dogs 72 and 73 project 'forward from their respective levers and 71 and each of said do has its left-hand face made abrupt and its right-hand face made inclined and said dogs are adapted to be operated by means of two tappets 78 and 80. The tappet 78 consists of the upper end of a bracket 81, Figs. 2, Il and 6, secured as by screws 82 tothe top of the totalizer 7. Said bracket extends from said totalizer toward the right and upward and the tappet 78 consists of a rearward projection of said bracket adapted' to engage the dog 72 but not to engage the dog 7 3, as the carriage travels back and orth. The tappet 8O consists of a like rearward projection from a bracket 83 similarly secured to the totalizer G and similarly formed except that it projects only high 'enough to engage the dog 73. The parts are shown in Fig. l in the position they occupy when the operator is about to strike a key to write the last digit in column 7 corresponding to totalizer 7 Tappet 78 is in such osition with relation to the inclined edge o dog 72 that during that step of the carriage i1nmediately following the writing of said last digit said t-appet will act on said dog tending to rock it clockwise in Fig. 4. As the dog is prevented by the pin 76 from rocking in that direction about its own pivot 7 Ll it will rock the lever 70 clockwise and push the wire 62 toward the' right, thus releasing latch lever' 56 and allowing locking lever 53 to drop to locking position. that is to say, in such position as to press locking lever 35 back to its locking position. The tappet 78 during the same step ot' the carriage, passes dog 72 and allows lever 70 to return immediately to normal position. In the same way locking lever 54; will be released by ta pet S() acting momentarily on dog 73 at t ie end of the adding column controlled by totalizer G. When the carriage is drawn back toward the right the tappets 78 and 8O engage the abrupt lett-hand faces of the dogs and rock said dogs about their pivots 74 and against the tension of their springs until each tappet escapes from its dog when the dogs will immediately be restored to normal position. The levers 70 and 7l are therefore not operated when the carriage is moved toward the right but are operated when it is moved toward the left.

It.' will be perceived that the lock can be thrown in at any desired position in thc travel of the carriage by suitably locating the totalizers 6 and 7, and that in setting up the machine for any particular piece ot' work one of these totalizers7 or another similarly equipped7 could be set wherever it was desired to test the clearance of one or the other of the cross totalizers 23 and 24.

lVhen the machine is locked at the end of the sixth column, by the means that have just been described, it is immediately there-V after unlocked by means in the cross total- -izer 2l. provided said cross totalirfer is clear at the time. as it should be; and when the machineis locked at the end of column 7 it .is simi arl-y unlocked by means included in the totalizer S23. The means'included within the cross totalizers 23 and 24, for thus unlocking the machine in case the appropriate totalizer is clear, is substantially identical with that shown and described and claimed in mv prior application for Letters Patent, sr. No. 462,628, filed Apr. i9, 192i, and said means is sutiiciently well shown for the purposes of the present application in Figs. 2 and 7 of the drawings. Each of said totalizers is, with certain exceptions to be presently pointed out, of the ordinary construction o Wahl totalizers. including certain carrying gears S4; 'which transmit motion by means ot idlers, not shown, to the pinions 85 ot the dial wheels 8G, said pinions and Wheels being rotatably mounted on a shaft 87 in the totalizer. Each of said pinions 85 has one shortened tooth 88 which, when the dial wheel 86 shows a 0 through the sight-opening,v stands in the position shown in lig. 7 where it co-operates with one tooth of a feeler comb 90, which comb is pivoted at 91 in the side plates of the totalizer. -This comb 90 includes a. series of' thih teeth or blades which pass between the dial wheels 86 in the planes of the pinions 85. When any one, or more, of said pinions has one of its ordinary long teeth .presented to the comb 90 Isaid comb is held init'srearmost position, but when all of the dials'are lined up in their zero positions so that everyone of the pinions 85 presents a short tooth'to the comb 90, then Said comb can rocktowa'rd the front of the machine to the position 'shown' in Fig. 7. At its right-hand end this feeler comb has an arm 92 extending therefrom rearward and having a tooth 93 'at its end which engages a notch in the forward end of a lever arm 94 which is pivoted-on one of the cross bars 95 ordinarily present in the Wahl totalizer. Thelever ar'n94is one arm of a bell crank which has also an upstanding arm `96 which constitutes a trigger that projects out through the top casing plate of the totalizer which is made with a slot for the purpose. A spring 97 actingon the arm 94 tends to move the parts to the position shown in Fig. 7; that is to say, to the position they occupy when the totalizer is clear. At such time the arm 96 occupies' its rearmost position but if any one of the pinions 85 be turned to bring a long tooth opposite the feeler 90, said arm or trigger 96 would be moved at its upper end toward the front of the machine. 1

The locking lever 54 hereinbefore referred to has an arm 100 projecting therefrom approximately horizontally toward the left and has near its left-hand end an inclined part 101, Fig. 2. The construction is such that when at the end of column 6 the lever54 is freed, this;A arm 100 drops down from its normal position shown in Fig. 2 to a lower position where it operatesthe locking lever 35. On the same step of the carriage, however, which releases this lever the cross truck 25 is released and makes its jump toward the right. 'If at this time the said totalizer is clear the arm 96 will occupy its rear position shown in Fig. 7, in which position the now depressed arm 100 is directly in its path. Said arm 96 therefore encountering the incline 101, cams the lever arm 100 upward, thus restoring the lever 54 to its normal position and the latch 56 immediately locks it there. If however, the totalizer 24 is not clear at the time, the arm or trigger 96 will occupy its forward position and in its motion toward the right will move in front of the arm 100 and not engage said arm so that said arm will remain in its lower position and the machine will remain locked.

As shown in the drawing and perhaps most clearly in Fig. 3, the lever 53 has an Aarm 102 projecting leftward therefrom as much further than the arm 100 as the totaL izer 23 is tothe left of totalizer 24. This arm 102 has annif-set part103 to bring its the same purpose as the incline 101. The,

totalizer 23 is equipped with a trigger 96 and the controlling mechanism therefor precisely as in the totalizer 24, and the parts operate in the same way, except that the trigger 96 for totalizer 23 acts on the lever 102 instead of on the lever 100. It will thus be seen that there vare two complete clearance proof mechanisms provided, one for each of the cross totalizers. When lever 54 is tripped ofi' `to lock the machine it will be moved to unlocking position-only in case the totalizer 24 is clear, the state of the totalizer 23 having no effect on this lever; and similarly the locking lever l53 can be released only by the totalizer 23 and not by the totalizer 24. It will thus be seen that the machine can be so set up as to test for clearance, at any point in the travel of the carriage, of either of these totalizers independently of the other.

In case one of the totalizers is not clear when it should have been and the machine is thereby locked up, as soon as the operator notices that the machine is locked up and observes the cause of it the clearance proof inechanism-will have performed its function. The operator can then readilyrelease V the machine by raising the depreed lever arm 100 or 102'by hand and can then proceed to correct the error in the usual way.

' From whathas been Said i-t will be perceived that the lever 53, 102 constitutes what may be called a warning device to warn the operator that the totalizker is not clear, and that the lever 54, 100 is similarly au'warning device for the totalizer 24.

It is desirable though not essential to provide a visual indicator to show that one or the other of the totalizer's 23 and 24 was not cleared when it should have been. To this end I have constructed the lever arms 100 and 102, as best shown in Fig. 3, where it will beseen that each of them has at an appropriate place in its length been rolonged upward to make a t-arget 105, eac of which targets has a streak or red 106 thereon. The balance of the target may be of any suitable color, preferably the same color as the casing plate presently to be described, so that when the lock is not lin operation this target construction is inconspicuous. Said casing consists of a plate 107, Fig. 4, spaced a short distance in front of the casting 13 to which it is secured by screws 108. This casing plate has two sight openin 110 suitably located so that when one o said targets 105 is down its red .stripe 106 will show through said slot. This visual indica tor is useful because adding machines con tain a number of loclrs and where the operator iinds the machine locked against operation it is useful to have some such indicator or bracket as this to show at a glance what the trouble is. ln the present instance if a red strealr shows through the left-hand slot il() it indicates that the left-hand tota-lizer 23 should be clear but is not and a s'nnilar trouble with the right-hand totalizer 24 is indicated by a red streak showing through the right-hand slot 110. lso igt the operator is alert he will see this streelt` even before he tries to operate the machine and finds it locked. it of course will be understood that this indicating device or somethingvequi-valent can also be used in the simplerjorm oi clearance proof mechanism shown in my prior application Sr. No. 462,528, liereinbe-` fore referred to.

Each or the lever arms l() and 102 is shown with a pin lll projecting rearward therefrom, Figs. 2, 3, and el, and each of said pins passes through a key-hole slot i12 in thev trame plate 50. The pin has an annular groove turned therein and the enlarged part oi"- the slot 112 is big enough to admit the full diameter the pin but the curved part of the said slot is only large enough to admit the reduced part of the pin. This construction brace@ the arms 1GO and 102 against displacement front and back and prevents them from getting out of proper alignment for proper feo-operation with the triggers 96.

ln my prior application for Letters Fatent, tiled August l5, 192i, Si'. No. 492,- 396, have shown a clearance proof mechanism applied to the accounting machine shown and described in the aforesaid lWahl patent, lilo. 1,349,024 and adapted to test for clearance the two cross-footers shown in said patent, one of them at one point and the other at another point of the carriage travel; and said prior application contains claims broad enough to read on the construction of the present application. By my present construction, unlike that shown in my said prior application, the act of proving clearance of one totalizer is independent of that of proving clearance for the other totalizer so that by present construction it is possible by suitably arranging the two tappets 'i8 and d@ to prove the. clearance 'for both totalizers at once in case such a thing is desirable. This would preferably be done hy mounting both "capp-ets on one b 'aclrct Moreover, my present construction is not limited in its application to two totaiizers. l have shown means for proving cle-arance o' two totalizers but it is obvious that the scheme can be extended to a large number which could not be so readily done in the construction shown in my earlier application. Moreover, the present construction is simpler and better mechanically than my prior construction.

acta

in short, the present construction is an ad,- vance in. several respects over that shown in my said prior application. y

Various changes may he made in the details ot' construction and arrangement without departing from my invention.

In a calculating machine, the com-f bination with -a traveling carriage and a jumping cross totalizer, of a lever extending transversely of the ^machine adjacent the path of travel of said jumping totalizer, means for tripping said lever at predetermined times and allowing it to drop down to non-clear position, means in said totalizer for immediately restoring said lever in case the totalizer is clear, and a colored target upon said lever arranged to show a spot of color above said totalizer when said lever is in non-clear position.

9. In a calculating machine, the combination with a traveling carriage, aplurality of jumping totalizers and means for operating the same, of clearance proof mechanism for said jumping totalizers including a plurality of targets mounted on the stationary framework one in the lvicinity of each of the jumping totalizers,'and means whereby the appropriate one ofsaid targets displays a visional indication in case one of said jumping totalizers Ais not clear when it should be. v

10. In a calculating machine, the combination witli a traveling carriage, a-plurality of totalizers and means for operating said totalizers, of a plurality of tappets on said carriage and traveling in dierent paths, a clearance testing device in each of said totalizers, and independent trains of connec tions extending from the respective tappets tothe respective clearance testing devices.

11. In a calculating machine, the combination with a traveling carriage, a plurality of cross totalizers, and means for operating saidtotalizers, of a plurality of independent clearance proving devices for therespective totalizers, each of said clearance proving devices being controlled independently of another such deviceby the travel of said carriage. y

12. In a calculating machine, the combination with a traveling carriage, a jumping cross-truck, a plurality ocross totalizers mounted on said truck, clearance proof mechanism for each of said totalizers, and a plurality of means each independent of another, whereby said carriage controls said clearance proving mechanism.
